LAST.

Appncation med April 2s, 1924. seriaifNo. 709,475;

- T o all whom t may concern.:

-citizen' ofthe United States, residing at Portsmouth,y in the county ofScioto andv State of Ohio, have invented certain new and usefulImprovements in Lasts, `of which the following is av specification,reference being had therein to the accompanying drawing.

My invention relates to lasts, and in particular to collapsible lasts.

It is the object of my invention to provide a collapsible last' in whichthe halves of the last rock upon one .another about a common center.

It is a further Object to provide yielding means to resist this movementfrom one position to the other. It is a further object to provide aconnecting means' the points of connection of which on each last halfwill be below the pivotal center'of the last halves when the last isexpanded and above said ycenter when the last is collapsed.4 K It is afurther object of my invention to provide an articulated connectinglink'betweenthev last halves which willpermit of the 'movement of-saidlast halves Vabout one 4 another although thepoints i of connectionpoints of connection will tend to vary as the of .thelink parts to therespective last halves are .xed and the distance between said t awayportion 2 for receiving a portion of i' lticallowerportion 5 whichacorresponds to ajsimilar portion Gon, thev frontofV the lower;

the iconnecting-m`echanism- A l The front half of the lastisnprovidedwith avertical rear face or substantially vertical vface 3, the lowerportion of which is cuty ,away in a semicircular concavity 4. lThis rearface terminates 1n the substantially very part ofthe rearorflheelportionofthe-flast,

7. This front -face l ofthe heel fpart l of. the

-last isprovided with a semicircula'r projection or shoulder l8which-describes .an arc somethingfgreater than 180 -degreesw Theupperpart of the front face lof the heel-part of the last is extendedupwardly and rearwardly as at 9 so that the space betweenlthe faces 3and 9 permits `thevlast-halves to collapse while thefaces 5 and 6limitktheir movement in their expanded position. f The knuckle jointcomposed ofthe shoulder 8 and concave depression 4 provides a suitableball and socket type of joint forvthe pivoting of the last partssubstantially about the center 10. The rear half of this last is alsocut away as at 11 to receive some ofthe connecting parts. The front partof the ,last is provided with a transverse piny 12fand the rear or heelpart of the last provided with a transverse pin 13.

l A semicircular link segment 14 is 4pivoted near one end-on the pin 12.It is piv'otally connected at its other lend on 'the pin15 to the endsofA connecting plates 16 and 17. The `free end of this link segment is.composed of an upper, substantially vertical portion- 18and acutawayportion. 18, so that this --end can rockupon a similarly formedend of a companion, oppositely disposed, link segment 19, which isV.connected at 2O to` the other ends of the connecting plates 16 and 17.The .segmentallink 19 is pivotally mounted on. the .pin .13.. V TheIlower ends of the llinks 14and. 19 are. provided withdownwardlyextending, oppof sitely disposed hooks; The hook on the link 14 isdesignated 21 and the hook on the link 19 isl designated 22.N Mountedongthese hooks and connecting them isa .coilfspring `23 which-servestoresist the rocking of the Ilink segments on the pins 12 and 13.

the spring with the linksegmentsis always below the pivotal center 10and is below the points of connection ormounting ofthe Ilink segments onthe respectivepinsvj12and 13. It will-be noted that theflast, whichisfp'ref-V erably made of wood, is somewhat compressible, vwhich isamatter Iof advantagefdue to the fact that the distance between thecenters of the pins 12 and 13 lwillincrease `and decrease as the partsare moved from collapsed to. expanded Aposition or viceversa. TheSpring' .23mw11eresistthsi-irirementbecause the linksegments,fwill-:roelsgnfthe spins 12 and 13 and the ends of these linksegments will rock upon one another during this movement from oneposition to the other of the last halves. y

It will be understood that I desire to comprehend within my inventionsuch modiiications as may be necessary to adapt my invention to varyingconditions of use.

I-Iaving thus fully described my invention, what I claim as new anddesire to secure by Letters Patent, is:

l. In a last, a toe part and a heel part adapted to rock about on oneanother, segmental links mounted in either part, adapted to have theirtree ends rock on one another, and yielding means connecting their otherends, whereby when the last partsare moved from one position to another,such movement will be yieldingly resisted and said segments will rock onone another.

2. In a last, a heel'part and a toe part adapted to rock upon oneanother, an articulated link connecting said parts, means to pivotallymount the ends lof said link on the respective parts and yielding meansccnnected with said linkto resist the movement of the parts from oneposition to the other.

3. In a last, a heel part and a toe part adapted to rock upon oneano-ther, an articulated link connecting said parts, means to pivotallymount the ends of said link onk the respective parts and yielding meansconnected with said link to resist the movement of the parts from'oneposition to the other, the points of connection of the link to the lastparts being below vthe point about which the parts pivot when the lastis expanded and above such point when the last is col'- lapsed.

4. In a last, a heel part and a toe part, a shoulder on one part havinga semicircular surface fitting into a semicircular depression on theother p art and said last parts being cut away so as to permit theircollapsing yand so ,as to limit their expansion,

and an articulated link connecting said parts arrangedctor the parts ofthe link to rock upon one another as ythe parts of the Y lastv pass fromone position to the other.

5. In a last, a heel part and a toe part, a shoulder on one'part havinga semicircular surface fitting into a semicircular depres sion on theother part and said last parts being cutaway so as t0 permit theircollapsing and so as to limit their expansion, an articulated linkconnecting said parts arranged for the parts of thev link to rockv uponone another as the parts ot the last pass from one position to theVother, and

yielding means connected lto the tree ends of said link to resist thismovement of the last parts.

6. In a last, a heel part and a toe part, a shoulder on one part havinga semicircular surface fitting into a semicircular depression on theother part and said last parts being cut away so as to permit theircollapsing and so as to limit their expansion, an articulated linkconnecting said parts arranged tor the parts of the link to rock uponone another as the parts of the last pass trom one position to theother, and yielding means connected to the free ends of said link toresist this movement ot the last parts, the points of connection of thelink on the last parts and the yielding means being located below suchpoints ot connection. I

In a last, last halves comprising a toe part and a lheel part adaptedto rock upon one another about a common center, an articulated linkjoining said last halves, said link being mounted Von transverse pinsmounted in the respectiveV halvesot sai-d last, and a spring connectedto hooks carried on the tree ends of said link below the points ofconnection ot the link to the last halves, said points of connectionbeing arranged so'that the movement takes place.

8. In a last, last halves comprising a toe part and a heel part adaptedtorock upon one another about a common center, an articulated linkjoining said last halves, said link beingy mounted on transverse Vpinsmounted in the respective halves ot said last, and a spring connected tohooks car*- ried on the free ends of said link below the points ofconnection ot the link to the last hal-ves, said points of connectionbeing arranged so that a line drawn therebetween will pass over thepivotal center aboutwhich ,n the lasthalves move when the last halvesare moved from one position to the other, the distance between saidcenters of connection varying vas'the movement takes place, said lasthalves being composed of compressibl'e material to accommodate thepassing ot the last halves so connected from y.one position to theother.

9. In a last, a heel part, a. toe part, aV

transverse pin located Yin either part of the last, said parts beingarranged to rock on one another about a common center, a segmental linkmounted on Vthe respective pins having abutting ends partially cut awayto permit sai-d ends to rock on one another, connecting platesconnecting said ends and pivotally mounted on such ends of the linksegments and downwardly extending' connecting means on the lower ends ofsaid flink seg,- ments below theirlpoint's of connection on the last andyielding means mounted thereon connecting the lower ends of said linksegments whereby as said last parts move from one position to the othersai-d spring will be flexed andthe link segments will rock upon oneanother accommodating the movement of the last parts and yieldinglyresisting it.

l0. In a last, a heel part, a toe part, a transverse pin located ineither part of the last, said parts being arranged to rock on oneanother about a common center, a segmental link mounted on therespective pins having abutting ends partially cut away to permit saidends to rock on one another, connecting plates connecting said ends andpivotally mounted on such ends of the link segments and downwardlyextending connecting means on the lower ends or' said link segmentsbelow their points of connection on the last and yielding means mountedthereon connecting the lower ends of said link segments whereby as saidlast parts move from one position to the other said spring will beflexed and the link segments will rock upon one another accommodatingthe movement of the last parts and yieldingly resisting it, said lastparts being composed of compressible material to accommodate theextension of the distance between the points of connection of thesegments to the last parts.

l1. In a last, a heel part, a toe part, a transverse pin located ineither part of the last, said parts being arranged to rock on oneanother about a common center, a segmental link mounted on therespective pins having abutting ends partially cut away to permit saidends to rock on one another, connecting plates connecting said ends andpivotally mounted on such ends of the link segments and downwardlyextending connecting means on the lower ends of said link segments belowtheir points of connection on the last and yielding means mountedthereon connecting the lower ends of said link segments whereby as saidlast parts move from one position to the other said spring will beflexed and the link segments will rock upon one another accommodatingthe movement of the last parts and yieldingly resisting it, said lastparts being composed of compressible material to accommodate theextension of the distance between the points of connection of thesegments to the last parts, said points of connection being so arrangedthat a line drawn between their centers will pass over the center aboutwhich the last parts are pivoted as said last parts move from oneposition to the other.

12. In a last, a toe part and a heel part adapted to rock about on oneanother, and segmental links mounted in either part and adapted to havetheir free ends abut and rock on one another.
